This is not strictly a question and if it does not meet the criteria for entries on AskUbuntu, it should be deleted. However, I have been thinking on this for a while and thought this would be the best place to get the most eye balls on it.
I believe Ubuntu is on to something truly unique with the whole lenses and scopes idea. There has been a surge of third party lenses and scopes for doing all sorts of things over the past few months and I believe this is only the beginning. However, one major hindrance is the fact that there is no easy way to discover and install the lenses. One has to follow Ubuntu blogs to find out about them, and then add their individual ppa's in order to be able to install them.
I suggest that a section should be created for them on the Ubuntu Software Center and the USC can even feature some of them from time to time in order to provide much needed visibility for the third party lenses.
